>Moreover, since mathematics is largely a technical, as opposed to philosophical, discipline, it is not unreasonable that mathematicians should, in the main, get on with the business of pursuing their technical specialities without worrying unduly about foundational questions. But that does not give them licence to pronounce upon matters on which they have not seriously reflected and are ignorant, or to assume that expertise in some special branch of their subject gives them special insight into its foundations.
